How to duplicate (verb) an invoice

Thanks Will, yeah this is what I've ended up doing out of desperation. It ended up being 50 fields removed, with a bunch of loops and null checks to deal with subfields. It works for me, but it took some trial and error and I consider it a hack. I certainly wouldn't claim it's reliable for anyone else.

I've since repeated this technique to duplicate a Spend Money Transaction. "Only" 25 fields needed removing, some with subtle differences to an Invoice. Very hacky, but very happy to have something working.

Thanks for the support link - I tried to make sure I was in the right spot but still managed to miss that forum!

Hi hraftery​ , 
In theory you'd just raise it like you would any other new invoice, as you said, with some of hte key fields removed.

According to the linked docs:

https://developer.myob.com/api/myob-business-api/v2/sale/invoice/invoice_item/

The implication of the second is you should be removing:

• UID
• Lines.RowID
• Lines.RowVersion
• LastModified
• RowVersion

• LastPaymentDate

  
  I'd also consider if you need to remove any of these related to Terms
• Terms
  

  It might be safest just to drop the entire Terms section, so they refresh off the customer.  If you aren't going to drop the entire terms section at least consider:

  • Terms.DueDate
  • Terms.DiscountExpiryDate
  • Terms.BalanceDureDate
  • Terms.DiscountDate
• Order
  If you are Duplicating an invoice, then you probably need to make sure you're not linking the wrong sales order. (Or raise this via the Sales Order process instead)

Note: I haven't directly worked with the AccountRight/Business API in a very long time, so I can't be treated as an authoritative source here.  If you need full help with that API reach out to the team via the help centre:
